What is Reinsurance?

Real Estate Dictionary

< Return to Dictionary Search

A contract which one insurer makes with another to protect the first insurer, wholly or partially, against loss or liability by reason of a risk under a separate and distinct contract as insurer of a third party. Reinsurance differs from coinsurance in that, in the case of reinsurance, only one insurer has a direct contractual relationship with the insured, and that insurer (commonly referred to as the "lead insurer") purchases reinsurance in order to lessen or spread the risk. The "lead insurer" will assume a risk up to a limit (the amount of which is referred to as the "retention") and any loss which exceeds this limit would be borne by the reinsurers. In the case of coinsurance, each coinsurer has a direct contractual relationship with the insured, and the risk is shared in agreed-upon proportions from the first dollar of loss.
